Sustainable Design Strategy of Regional Revitalization Based on AHP–FCE Analysis: A Case Study of Qianfeng in Guangzhou

Abstract

As urbanization progresses, large cities continue to attract population, causing depopulation and regional development imbalances, especially in remote rural areas facing sustainability challenges. This study aims to explore local resource potential and assess critical factors for regional revitalization, offering design strategies to promote local sustainability. The study is based on the UN Sustainable Development Goals (SDGs) and assesses the status of regional development through field research. The Delphi method was employed to interview experts and build a multi-tiered sustainable development evaluation indicator framework (Level 1: B1–B3, Level 2: C1–C8, Level 3: D1–D16), covering economic, social, and environmental dimensions. The weights of the indicators were determined through the analytic hierarchy process (AHP), and the fuzzy comprehensive evaluation (FCE) method was applied to comprehensively assess the sustainable development status of Qianfeng Community. The research findings revealed that due to population outflow and a lack of participation in co-building channels, the region scored lowest in “local employment & entrepreneurship (D2)”, “innovation & entrepreneurship culture (D10)”, and “endogenous development (D16)”. Consequently, the study proposes the establishment of a regional revitalization co-creation platform based on “life projects” as part of a sustainable design strategy. These research results provide valuable case studies and strategic references for future regional revitalization and sustainable design initiatives.
